Hilarious song

I was listening the weekly "Car Talk" podcast. They take several "breaks" in the show, during which they play car-related songs. To be completely honest, I always always skip them because the music is typically horrible. However, on this occasion I instantly recognized the notes of Beethoven's "Moonlight Sonata". In addition to the expected piano were hilarious lyrics about a driver being stopped at a red light. The melody of the song turns into drivers "beeps" of their horns.

It turns out the song is by a group called "Beethoven's Wig" that turns Classical songs into sing-a-longs (basically for children). You can preview and/or buy the song on iTunes.
